Ted Cruz won the Utah Republican caucuses, advancing his effort to block front-runner Donald Trump from securing a majority of presidential nominating delegates before the Republican convention in July.

The Texas senator’s victory in the heavily Mormon state came after 2012 GOP nominee and Utah resident Mitt Romney urged Republicans to back anyone but Trump as part of the GOP establishment’s fight to stop the New York billionaire from clinching the nomination.

With the attack in Brussels refocusing the presidential campaign on the issue of terrorism, Hillary Clinton said Tuesday that Republicans would make the country less safe.

“In the face of terror, America doesn’t panic," she said in a high school gym in Seattle. "We don’t build walls or turn our backs on our allies.”

Clinton sharply criticized the leading GOP candidates for their national security proposals, which involve barring Muslims from the country, scrutinizing Muslim neighborhoods or scaling back America's involvement in international alliances.
